Using MUI @Next and the TextField component.
MUI very nicely adds a little * at the end of the label when you add required as a prop, however it seems to not work out of the box when you add the endAdornment in order to enable a "show password" toggle.
I have created a codesandbox of my issue.
The regular <Texfield />
component shows the * as expected, but the also required password field doesn't.
